The RTL-SDR dongles get most of the love from people interested in software-defined radio, but the Pluto is also a great option, too. [FromConceptToCircuit] shares code to turn one of these radios ...

[MrCircuitMatt] has been doing a lot of radio repair recently, quickly realized having a spectrum analyzer would be a useful thing to have. Why buy one when you can build one, he thought, and he ...

Back in the 1960s, when I started working in radio broadcast engineering, an oscilloscope was my “eye” on what was happening with equipment. That tool served me well and is still in daily use in my ...

This application note discusses on using a passive probe which is commonly used in an oscilloscope, only in this case, it will be used for a spectrum analyzer. A portion of the preferences and ...

Like most modern radio communications devices, wireless local-area networks (WLANs), RFID tags, and 3G cellular systems rely on complex modulations that require specialized signal-analysis ...

A spectrum analyzer with a tracking generator can be a useful piece of test gear. This application note covers making a simple loss measurement on a coaxial cable with BNC connectors. Two N-type to ...

Using a spectrum analyzer to measure noise signals requires several additional factors, such as sensitivity or how well the instrument can measure small signals. The analyzer’s noise floor specifies ...

This file type includes high resolution graphics and schematics when applicable. Designers sometimes need to analyze the spectrum of a modulated carrier. Although they can do this by down-converting ...
